While the lists are used mainly for development, user queries are welcome. No need to subscribe for a one-off question, just send an email. You may also want to check the various qemu resources on the web, as kvm shares the qemu user interface and networking.

Please observe the usual mailing list etiquette: don't top-post, and trim excess quotations from the mail you are replying to.

Don't post to individual kvm developers directly.
